INDEX.

' SPECIFICATION forming part or Letters Patent No. 288,277, dated November 13, 1883.

' Application filed April 11, 1883. (No model.)

To all whom, it may concern:

Be it known that I, LEWIS B. Tnnnn'r'rs, of St. Louis, Missouri, have made a new and useful Improvement in Indexes, of which the following is afnll, clear, and exact description, reference being had to the annexed drawings, making part of thisspecification, in which- Figure 1 is a View in perspective of a book having the improvement, the book-cover be ing opened and the index being closed against the cover; Fig. 2, a similar View of the book, the index being opened out from the book; Fig. 3, a View showing the index drawn out and the book and index both being opened; and Fig. 4., a View similar to thatof Fig. 1, saving that the index is in a different position.

The same letters denote the same parts. The present invention is an improvement in that class of indexes which are permanently attached to the books to which they belong, but capable of being opened out therefrom to enable both book and index to be simultaneously opened.

The improvement relates to the peculiar mode of uniting the book and index.

The book A and index B are each of the usual form.

G G represent arms jointed at one end to the book-cover aandI at the other end to the index. The, connection with the book-cover is at or toward its outer edge, a, and with the index at its back b, and so that the arms can swing upon their points of connection with the book-cover and the index in turn upon the the book, as in Fig. 1, and to be drawn out fronrthe book, as in Fig. 2, and 'when thus drawn out capable of being opened Without causing interference with the turning of the,

book-leaves. The index can also be turned upon the arms 0 C, so as to bring the index either into the position of Fig. 1 or that of The preferable mode of constructing the arms 0 C is that shown, the arms being extended at 0 C forming, in efl'ect, a square frame justlarge enough to admit the index as the latter is turned to and fro into the Various positions above described. The frame is connected with the index and book by means of the staples c c. r

The index might, instead of being connected with the edge a of the book-cover, be connected with the top or bottom edge of the cover, and either at the front or back of the book.

It will be noticed that the index can be opened Without necessarily Withdrawing it from the book. V

. I claima 1. The combination of the book A, the in-' dex B, and the arms '0 C, substantially as described.

2. The combination of the book A, the index B, the frame 0 C C G, and the staples c a, substantially as described.
